Go ahead and increase the calcium in your flock diet and offer crushed eggshell or oyster shell as a supplement. Offer yogurt as a treat.

That was interesting to see, thank you for sharing! Sometimes it happens that a formed egg instead of making it's way out, reverses back and gets incased in a new egg forming. The cause of this is unknown.

Thank you, that seems like the most logical answer for the unexplained video.
